Digital BW, The Print

I thought I would share my experiences.  This does take a fair amount 
of time to get started, and I'd be interested in any feedback.

I am trying to set up black and white printing with MIS UT2 inks on an
Epson 1280.  My first attempts, using the Roark curves in PhotoShop6
have been troubled with ``posterization.''   I looked through the
newsgroup, and there seem to be intermittent but persistent complaints
about this, and various approaches.  To my reading, there doesn't 
appear to be a consistent solution.  

While playing with this, I decided to try a black-only print with the
MIS Eboni black.  This doesn't have the posterization, and has a nice
tonal range.  Much better than my previous results with the full UT2
set.  The only problem with the black-only is the perceptible 
dot/dither pattern.  Which isn't so perceptible from viewing distance.

Next, I tried QuadTone RIP.  I couldn't get it working correctly on
Linux, but I have an old version of Mandrake, and that is probably the
problem.  I set it up on one of our home-networked computers that has
XP, and then print to the printer attached to the original computer, 
now booted as windows98se in order to share the printer.  This does 
not seem to have the posterization problem and has a nice tonal 
range.  

Next I have to try to get the monitor to match the printer.  Then I 
will try to compare QTR and BO on similar prints.
